I missed "Old B's" exam and didn't take the B-level exam before March. Today, I decided to prepare for the B-level exam in Beijing in May. Looking at the 689 B-level exam questions and various numbers, units, and professional terms, it's really overwhelming. I want to ask experienced B-level exam takers for some tips and methods on how to practice effectively. Best of luck to everyone! Thank you!🙏🙏🙏
